Overview of the 3D seismic survey area and the distribution of VLFEs in the Nankai Trough. a Map of the survey area southeast of the Kii Peninsula, Japan. The black polygon indicates the area of the 3D MCS survey in 2006 (Moore et al. 2007). The red rectangle indicates the target area in this study, and the red dashed lines indicate the locations of vertical sections shown in Figs. 1b and 3. The yellow circles are the epicenters of VLFEs located by Nakano et al. (2018). The white squares denote the locations of ocean bottom seismic stations of the DONET. The magenta circle denotes the location of IODP Site C0006. b A vertical section along line IL25000 with vertical exaggeration (VE) of 1.5. The accretionary prism is divided into the inner prism and outer prism by a splay fault. Our study area enclosed by the red rectangle is characterized by imbricated thrusts and an underthrust succession above the oceanic crust
